Cyanoacetamide MCR (III): Three-Component Gewald Reactions Revisited

Benzannulated bicycles by three-component aryne reactions.

Disparity Component Matching Revisited

In this paper, we demonstrate how the quality of disparity maps could be improved by applying windows that adapt their shape. In our approach, windows adapt to high-correlation structures in disparity space, which we call the disparity components. The shape of adaptive windows is found by projection the disparity components to the input images, which results in two non-rectangular windows. The ...

Mechanism Discrimination for Bimolecular Reactions: Revisited with a Practical Hydrogenation Case Study

The governing mechanism of surface reactions is a fundamental concern in heterogeneous catalysis. The Langmuir–Hinshelwood (LH) mechanism is widely accepted to control the surface reactions in many catalytic systems. This contribution derives and compares several important surface rate equations to evaluate their quality of fitting to the experimental data collected for a vapor-phase hydrogenat...

Multiplex PCR for detection of plasmid-mediated colistin resistance determinants, mcr-1, mcr-2, mcr-3, mcr-4 and mcr-5 for surveillance purposes

Background and aimPlasmid-mediated colistin resistance mechanisms have been identified worldwide in the past years. A multiplex polymerase chain reaction (PCR) protocol for detection of all currently known transferable colistin resistance genes (mcr-1 to mcr-5, and variants) in Enterobacteriaceae was developed for surveillance or research purposes. Methods: We designed four new primer pairs to ...

Thiazole formation through a modified Gewald reaction

The synthesis of thiazoles and thiophenes starting from nitriles, via a modified Gewald reaction has been studied for a number of different substrates. 1,4-Dithiane-2,5-diol was used as the aldehyde precursor to give either 2-substituted thiazoles or 2-substituted aminothiophenes depending on the substitution of the α-carbon to the cyano group.
